I'm not saying that. I'm saying there's a difference in the usage between Sparda's bloodine using it and other people using it. It is limited in comparison so far. Nero fixes the sword. Agnus could not. The difference in that situation: Nero is revealed to be related to Sparda. Agnus is not There's a unique connection between the Yamato and the user when they're of Sparda's Bloodline there (Nero in this instance). Even the Yamato wiki page notes this. It's there. Point blank.

Rebellion, being a similar weapon in the fact it's a keepsake meant for a son, works in a very similar way. It reacted to Dante's blood and unleashed his devil trigger. And it's a fact that despite it being passed down from his father (DMC4 Intruction Manual), it's became his physical manifestation of power. Yamato did the same for Nero. These weapons do have a connection with those related to Sparda. It's there, point blank.

When Agnus used it to open a hellgate, that didn't require a unique connection. There was a blade hole for it. When Sanctus stabbed Nero's Devil Bringer, he used the sword in a basic manner. It's still a magic sword regardless so it got Nero's Devil Bringer.

Is there evidence saying no one else outside Sparda's family can use it amazing capabilities? NO. But is there also evidence saying they can't? NO! Is there evidence that there's a unique connection between Yamato and a user of Sparda blood? YES! Nero's instance shows this. Agnus stated he could not. Nero did. That shows a connections is there.

Beowulf is not a keepsake from Dante/Vergil's father. It's capabilities and abilities are far different. It's a Devil Arm sure but it's not the same.
